This guide lays out what each vendor publishes.
The Quick Answer

Understanding the Core Difference
MailerCheck is Email list verification and deliverability testing tool that validates single addresses, bulk lists or new signups through an API, and tests email content and inbox placement before a send.
We-Connect is LinkedIn intelligence and outreach platform that combines LinkedIn automation with email sequences in one workflow.
